Question

What is the mass of the air in a room measuring 10m x 5m x 2m. If the density of air is 1.3g/cm^3

Answer 1

D=m/v

Answer 2

So v= 10m x 5m x 2m = 100m^3
D = 1.3kg/m^3
D = M/V M= DxV
m = 1.3kg/m^3 x 100m^3
M = 130 kg

Answer 3

So 1.3=m/(10x5x2)

Answer 4

So
1.3=m/100
m=130

Answer 9

@TheSmartOne But the density was 1.3g/cm^3
How did those change?

Answer 10

demsity is 1.3 but the mass is 130kg

Answer 11

@TheSmartOne What I don't understand is cm^3 x m^3
